CRQSS-CLEVIS.

SPECIFICATION forming part of Letters Patent No. 599,204, dated February 15, 1898. I

Application filed May 12, 1897.

To all whom it may concern:

Be it known that I, J OHN' LEWIS THOMAS, of Osceola, in the county of St. Clair and State of Missouri, have invented a new and Improved Oross-Clevis, of which the following is a full, clear, and exact description.

The invention relates to cross-clevises, such as shown and described in the application for Letters Patent, Serial No. 629,042, filed by me on March 24, 1897.

The object of the present invention is to provide a new and improved cross-clevis, arranged for convenient attachment to the clevis-jaws of a plow-beam and adapted to be conveniently adjusted to any kind of plow.

The invention consists principally of a clevis-body, a clevis-pin held removably on the said body, and an arm adjustable on the clevis-body and formed with a fork for receiving the clevis-pin and one of the jaws of the plow-beam.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan View of the improvement with the plow beam and jaws in section. Fig. 2 is a similar view of a modified form of the improvement with the jaw in section. Fig. 3 is a similar view of another modified form of the improvement with the jaw insection. Fig. 4 is a perspective view of the adjustable arm shown in Fig. 1, and Fig. 5 is a plan view of the improvement arranged as a three-horse clevis.

The improved device as illustrated in Fig.

' 1 is provided with a clevis-body A, having a row of apertures A for connection with the usual ring or other device. On one end of the body A is formeda lug A in which is held removably one end of the clevis-pin B, the latter being preferably screwed in the said lug A as indicated in the drawings. The clevis-pin B is adapted to pass through the apertured ends of the jaws O and 0, attached to the outer end of the plow-beam B, and the said clevis-pin also passes through apertures in an arm E, fitted to slide on the body A,

Serial No. 636,216. (No model.)

the said arm being provided for this purpose with an opening'E, as plainly indicated in Fig. 4. The arm E is provided with a fork' .the pin B, as shown in Fig. 1, or, as illus trated in Fig. 3, the body A is formed with two lugs A A, through which passes the clevis-pin B and between which the jaw (J is held. The pin B may pass, through both forked members of the arm E, as illustrated in Fig. 1, or only through one of the same, as shown in Fig. 2, the arm E having its forked member E terminating close to the pin B so as to prevent the jaw C from moving longitudinally on the clevis-pin.

It will be seen that by the arrangement described the several parts can be readily connected or disconnected with and from each other by simply unscrewing the clevis-pin B from the lug A and drawing it out of the jaws C C and the arm E or reinserting it through the said parts to finally screw it in the lug A to hold the several parts connected with each other.

Now by the arrangement described the clevis can be readily used on plow-beams having jaws of different width, as it is evident that the arm E is readily adjusted on the body A to receive one of the jaws of the plowbeam, the other jaw abutting against the lug A In the arrangement shown in Fig. 5 the arm E is locked by a pin F to the clevis-body A at one of its apertures A and the forked end E of the said arm receives the eye G of a brace G, secured to the pl0w beam D. The eye G is engaged by the clevis-pin B also engaging the jaws 0", attached tothe plowbeam. This arrangement is very serviceable for use as a three-horse clevis.

Having thus fullydescribed my invention, I claim as new and desire to secure by Letters Patent- 1. A cross-clevis, comprising a clevis-body,

a clevis-pin held adj nstably on the said body,

and an arm held adjustably on the clevisbody and provided with a fork for receiving the clevis-pin and one of the jaws of the plowbeam, substantially as shown and described.

2. A cross-clevis, comprising a clevis-body formed with a lug, a clevis-pin held removably in the said lug, and an arm held adjustably on the olevis-body and formed with a fork for the passage of the said clevis-pin, the fork being adapted to receive one of the jaws of the plow-beam, the other jaw extending close to the said lug, substantially as shown and described.

3. A cross-olevis, comprising a'clevis-body formed with a lug, a clevis-pin held removably in the said lug, and an arm held adj ustably on the clevis-body and formed with a fork for the passage of the said clevis-pin, the fork being adapted to receive one of the jaws of the plow-beam, the other jaw extending close to the said lug, and a second lug integral with the said body, to engage the inner face of the second plow-beam jaw to hold the latter between the said lugs, substantially as shown and described.
